Abstract
Ein Verfahren zum Senden eines Datenstroms in einem Mehrträger-Übertragungssignal zwischen einem Sender und mehreren Empfängern kodiert den Datenstrom (d[i]) in einen Datenstrom von Kodeworten (d[i]) mit einer Koderate (R), die kleiner oder gleich der inversen kleinsten Anzahl (P) von in jedem Empfänger jeweils verarbeitbaren Subträgersignalen (s 0(t),s 1(t),...,s N-1(t)) des Mehrträger-Übertragungssystem (s(t)) ist, verschachtelt Dateneinheiten von mindestens einem Kodewort des Datenstroms von Kodeworten (d'[i]) in einen Datenstrom mit verschachtelten Kodeworten ((d'[i]), multiplext den Datenstrom mit verschachtelten Kodeworten ((d''[i]) auf einzelne den einzelnen Subträgern des Mehrträger-Übertragungssignals (s(t)) entsprechende Sendedatenkanäle invers, moduliert die dem jeweiligen Sendedatenkanal jeweils zugewiesenen verschachtelten Kodeworte des Datenstroms mit verschachtelten Kodeworten (d 0 ''[i],d 1 ''[i], ..., d N-1 ''[i]) auf einen zum jeweiligen Sendedatenkanal (0,1,...,N-1) gehörigen Subträgersignale (s 0(t),s 1(t),...,s N-1(t)) und fügt sämtliche Subträgersignale (s 0(t),s 1(t),...,s N-1(t)) mit dem zum jeweiligen Sendedatenkanal (0,1,...,N-1) jeweils zugewiesenen verschachtelten Kodeworten des Datenstroms mit verschachtelten Kodeworten (d 0 ''[i],d 1 ''[i],...,d N-1 ''[i]) zu einem Multiträger-Übertragungssignal (s(t)) zusammen. A method of transmitting a data stream in a multicarrier transmission signal between a transmitter and a plurality of receivers encodes the data stream ( d [ i ]) into a data stream of codewords ( d [ i ]) having a code rate ( R ) less than or equal to the inverse the smallest number ( P ) of subcarrier signals ( s 0 ( t ), s 1 ( t ),..., s N -1 ( t )) of the multicarrier transmission system ( s ( t )), which can be processed in each receiver, is interleaved Data units of at least one codeword of the data stream of codewords ( d ' [ i ]) into a data stream with interleaved codewords (( d' [ i ]), multiplexes the data stream with interleaved codewords (( d '' [ i ]) to individual ones Subcarriers of the multicarrier transmission signal ( s ( t )) corresponding transmit data channels inverse, modulates the respective transmit data channel respectively assigned interleaved codewords of the data stream with interleaved codewords ( d 0 '' [ i ], d 1 '' [ i ], ..., d N - 1 '' [ i ]) to a sub-carrier signals ( s 0 ( t ), s 1 ( t ),..., S N -1 ( t ) belonging to the respective transmission data channel (0,1, ..., N -1) )) and adds all subcarrier signals ( s 0 ( t ), s 1 ( t ), ..., s N -1 ( t )) to the respective transmit data channel (0,1, ..., N -1) respectively assigned nested codewords of the data stream with interleaved codewords ( d 0 '' [ i ], d 1 '' [ i ], ..., d N -1 '' [ i ]) to a multi-carrier transmission signal ( s ( t )) together.
